Another null/puppet pin expression issue
Hiya –
Another tale of puppet pin/null expression woe.
Grabbed this expression to lock puppet pins to null anchor points, written just like this:
n=thisComp.layer(“null_name”);
nullpos=n.toComp(n.anchorPoint);
fromComp(nullpos);
Filled in the name of my null. Got everyone’s favorite: syntax error at line 1 in property ‘Position,’ etc etc.
Looked this issue up on the Cow forums, and tried all the magic fixes, many from Dan Ebberts himself.Tried this:
n=thisComp.layer(“NAME”);
nullpos=n.toComp(n.anchorPoint);
fromComp(nullpos);And just this:
n = thisComp.layer(“null”);
n.toComp(n.anchorPoint)Also this:
n=thisComp.layer(“null”);
fromComp(n.position);NOTHING. WORKS. No magic fix for me. Yet…?
Things to know:
1. The layer I am pinning is a precomp, which contains one layer;
2. There are 3 nulls in the main comp, none of which have been parented yet;
3. I have renamed the puppet pins based upon what they are controlling (eg. knee, toe, thigh)
4. I have tried these expressions with 3D ticked and un-ticked
5. I am using After Effects CC, build 2014.0.2 (13.0.2.3) on a Mac, running OS X 10.10.3 (Yosemite)Thanks!
n=thisComp.layer("NAME");
nullpos=n.toComp(n.anchorPoint);
fromComp(nullpos);

Your expression doesn’t generate any syntax errors for me. What’s the exact error message you’re getting?

Holy cow! (See what I did there?) Ebberts himself! Thanks for replying!
Here’s the error, along with the workflow:

Nothing jumps out at me. Can you copy and paste here the exact expression that’s generating the error? (I can only see the first line in your pic).

Oh, sure:
n=thisComp.layer(“ankle”);
nullpos=n.toComp(n.anchorPoint);
fromComp(nullpos);
See above re: “ankle.”
THANK YOU

That expression has curly quotes around the layer name, which will generate a syntax error. Try it this way:
n=thisComp.layer(“ankle”);
nullpos=n.toComp(n.anchorPoint);
fromComp(nullpos);Dan

Arg, those damned quotes! I’ve run into this before. Thought I’d tried it for that particular comp, but maybe not. Was probably a different error, as I tried to run DuIK on the 2014 build of AE CC earlier on – BIG MISTAKE. :/
Anyway: thank you, and it’s great to see you on here! Loved your ‘triggering animation with markers’ method. Saved my butt on a series of projects I did a number of years ago.
